Conformational switching within dynamic oligomers underpins toxic gain of function by diabetes associated amyloid

Nat Commun
PMCID: 5882805
PMID: 29615609
DOI: 10.1038/s41467-018-03651-9

[…] taking measurements. Autocorrelation data were collected at regular intervals (5 min) with each autocorrelation curve collected over 10 s with 30 repeats.Autocorrelations were fit using the software QuickFit3.0. For thiol-conjugates, a model for a single-diffusing species undergoing 3D Brownian diffusion was used.1G(τ)=1N×1+ττd,1-1×1+τs2τd,1-12,here, N is the total thiol-conjugated molecules in t […]


EGFP oligomers as natural fluorescence and hydrodynamic standards

Sci Rep
PMCID: 5020695
PMID: 27622431
DOI: 10.1038/srep33022

[…] tion function of the signal was calculated by an ALV-5000E correlator (ALV-Laser GmbH, Langen, Germany). Runs of 5 × 20 seconds were recorded. Autocorrelation curves were fitted by using the software Quickfit 3.0 to a model assuming 3D diffusion of a single component plus triplet state formation: where τ is the lag time, T is the equilibrium fraction of dyes in the triplet state, τtr is the tri […]


Imaging Fos Jun Transcription Factor Mobility and Interaction in Live Cells by Single Plane Illumination Fluorescence Cross Correlation Spectroscopy

PLoS One
PMCID: 4397054
PMID: 25875593
DOI: 10.1371/journal.pone.0123070

[…] by dividing the cross-correlation function by the smaller of the two auto-correlation functions: q=ggr(τ)min[ggg(τ),grr(τ)](1) where τ is the minimum lag time. All data evaluation was performed with QuickFit 3.0 []. […]


Investigating the Cellular Distribution and Interactions of HIV 1 Nucleocapsid Protein by Quantitative Fluorescence Microscopy

PLoS One
PMCID: 4344342
PMID: 25723396
DOI: 10.1371/journal.pone.0116921

[…] ment, 50 acquisitions of 5 seconds duration were realized and the autocorrelation curves were calculated. Five averages of ten autocorrelation curves were calculated and analyzed independently by the Quickfit software [], using the anomalous diffusion model: G(τ)=1Veff〈C〉1(1+(ττD)α)11+(r0zz)2(ττD)α(1) where Veff and represent the effective focal volume and the average concentration of fluoresc […]
